Egg Car Essay Example

I. Purpose: * In this project I built a car out of only paper, straws, wheels, and hot glue. The car was to protect and egg, comparable to how real cars protect us. If you built a car that did not protect the egg, it is comparable to you having been in a fatal car crash. II. Variables: * With the building of our cars, we were measuring the mass of the egg, mass of the car, time for it to go down the track, and the width so that it would fit down the track. The variable that affects our cars the most is the mass. If your car weighs to little, it will go at high speeds and the egg will most likely not be protected, but if the car weighs to much it might not make it all the way down the track. III. Materials: * 7-8 pieces of computer paper * 4 plastic bendy straws * Lots of hot glue * 2 sets of wheels and axles * 1 egg, large Grade A * Markers for decorating IV. Methods * To construct my project, I first began building the protection chamber for the egg. I glued 4 or 5 sections of paper together to make it sturdy and safe. I made a flap that tucked in so that the egg could not fall out. I then glued more paper together in the shape of a box. There was a base and a lid, sort of like a Christmas present. I put straws around the metal of the axle and glued them onto 4 pieces of straws glued to together. All that was left after that was to glue the box onto the straws connecting the wheels. I then filled it with some scraps of paper so the protection chamber could not move around. * The main problem I encountered while building my project was how to get the wheels off of a toy truck. I solved this problem with the aid of Mr. Farrand, 3 pairs of pliers, some very strong scissors, and a hammer. =] The other problem I encountered was that the wheels fell off after every test run. I solved this problem by simply gluing the wheels back on. V. Pictures
